Ivanka Trump recently assumed an official role in her father's administration. She moved into a West Wing office and obtained a security clearance in late March.

About 53% of respondents said the first daughter playing a significant role in the White House is not appropriate, compared with 36% who said it was appropriate and 10% who did not have an opinion.

Ivanka Trump walks with her husband, White House Senior Adviser Jared Kushner, toward Marine One while departing with her father President Donald Trump on February 17, 2017 in Washington, DC.

Kushner, her husband, also has a broad portfolio within the West Wing, where he has an influential purview over a range of foreign and domestic policy issues. He is heading up the Office of American Innovation, a new White House office aimed at reforming the federal government through private-sector solutions.

About 53% said his role was not appropriate, compared to 32% of respondents who said it was appropriate and 15% who did not know.

First family

About 56% of those surveyed had an unfavorable opinion of Trump, compared to 39% who had a favorable opinion of him. That compares with 31% with unfavorable opinions of Ivanka Trump and 36% with favorable opinions, and Kushner, with 32% unfavorable to 15% favorable. About half of respondents had not heard enough about Kushner to have an opinion.

First lady Melania Trump has a 34% favorable rating versus 24% unfavorable and 35% who have yet to form an opinion.

"When it comes to President Trump's immediate family, Ivanka and the first lady get so-so marks," said Tim Malloy, assistant director of the Quinnipiac University poll.
